Solve x=810^5-4*510^5left(2-0.5right)

$$x = 8 { 10 }^{ 5 } -4 \cdot 5 { 10 }^{ 5 } \left( 2-0.5 \right)$$

Solve for x

$$x=-2200000$$

Steps for Solving Linear Equation

Calculate 10 to the power of 5 and get 100000.

$$x=8\times 100000-4\times 5\times 10^{5}\left(2-0.5\right)$$

Multiply 8 and 100000 to get 800000.

$$x=800000-4\times 5\times 10^{5}\left(2-0.5\right)$$

Multiply 4 and 5 to get 20.

$$x=800000-20\times 10^{5}\left(2-0.5\right)$$

Calculate 10 to the power of 5 and get 100000.

$$x=800000-20\times 100000\left(2-0.5\right)$$

Multiply 20 and 100000 to get 2000000.

$$x=800000-2000000\left(2-0.5\right)$$

Subtract 0.5 from 2 to get 1.5.

$$x=800000-2000000\times 1.5$$

Multiply 2000000 and 1.5 to get 3000000.

$$x=800000-3000000$$

Subtract 3000000 from 800000 to get -2200000.

$$x=-2200000$$

Assign x

$$x≔-2200000$$
